sulfur cycle 中文意思是什麼
sulfur cycle
解釋
硫循環-
The understanding of biogeochemical cycle of hydrogen, oxygen, carbon, nitrogen, and sulfur elements in nature ecosystem have increased substantially in the past two decades owing to the improvement of gas isotope ratio mass spectrometer and the wide application of isotopic studies with these elements
摘要近20年由於氣相同位素比值質譜儀的改良和氫、氧、碳、氮和硫等穩定同位素的廣泛研究，穩定同位素的研究技術已實質增加我們對于這些元素在自然生態系中生地化循環的了解。 -
Man's effect on the sulfur cycle has been considerable.
人類對硫循環的影響一直是很可觀的。 -
The results indicate that these parameters in profile change closely with geotectonic cycles as follows : sulfur, colloid and asphaltene contents keep the lowest values in devonian, triassic, jurassic and tertiary ; they are in accordance with regressive geotectonic phases, of which the maximum values appear to be correspond to the largest - scale marine transgressions occurred in caledonian cycle, hercynian cycle and middle phase of alpine cycle
指出，這些石油參數在剖面上的變化與大地構造旋迴有密切關系：硫，膠質和瀝青質的含量在泥盆紀、三疊紀、侏羅紀和新近紀為最低值，它們與海退構造階段相一致；石油化學成分最大值與加里東旋迴、海西旋迴和阿爾卑斯旋迴中期的最大海侵相一致。 -
The well - understood natural sulfur cycle in relation to oceanic environment, the well - known natural reservoir, is described in section 1
第1部分闡述了已熟知的自然硫源海洋硫循環的了解。 -
The distribution and amount analysis of these bacteria in different layers of core sediment indicated that there was an intact cycle that coupled sulfur metabolism with methane metabolism existed in this area, which may be the microbial response to the environment because there was seldom similar bacteria detected from " manganese nodule " area sediment by dna - dna hybridization with specific oligonucleotide probe and 16s rdna clone library analysis
而16srdna克隆文庫分析和dna - dna雜交的結果表明「結核」區沉積物中這兩類細菌數目很少，說明「暖池」區沉積物中的微生物群落結構特徵是對環境因素的一種響應，同時也可能是影響該海區深海及海洋環境的一個重要因素。 -
Section 2 gives a fundamental picture of the terrestrial sulfur cycle with respect to the relative importance of its individual chemical components and of its source
第2部分給出了陸地硫循環的基本情況及各化學組分和源的相對重要性。 -
Finally, as conclusion and suggestion, the paper discusses the direction towards overcoming various problems encountered in measurements relating to the natural sulfur cycle in diverse natural ecological systems
最後的第4部分作為總結討論了克服早先自然生態系統硫循環研究測定中的各種局限的方向並提出建議。
